Performance check

Check your web app's response time

Times your server's initial response and flags anything above 2.5 seconds as a warning, 6 seconds as critical. Plus six other launch checks.

A slow initial server response is the most silent conversion killer. Before the browser renders a single pixel, it waits for the server. This scanner measures your server's initial response time and flags anything over 2.5 seconds as a yellow finding and over 6 seconds as a red. It also runs six additional checks for SSL, auth, payments, secrets, Supabase, and broken links.
